In the address field, is there a way to restrict the addresses that auto populate (via Zoho Maps or Google Maps) to a specific state (I know it's possible with the country). 

Additionally, how often does the address in Zoho Maps get updated? Certain addresses that should be prefilled are not provided, both new addresses or old (some addresses have existed for 70+ years that are not available via the autopopulated option).

Or is Google Maps just the more reliable/robust resource to use?
